Procedure

59.95 g-(0.010 m) α,β-di(1-methyl-aminoethyl) poly-(ethylene oxide-co-propyleneoxide) of MW 5995 (Jeffamine-ED 5000, TEXACO Corp.) and 59.95 g of anhydrous methyl propyl ketone are charged into a 3-necked round bottomed flask equipped with a stirrer, nitrogen inlet, condenser, thermometer and dropping funnel. The solution is stirred at room temperature under dry nitrogen. Then 3.10 g (0.020 mole) of 2-isocyanotoethyl methacrylate (MW 155) dissolved in 3.1 g of anhydrous methyl propyl ketone are added slowly from the dropping funnel. The mildly exothermic reaction is maintained at 35° C. and below by water bath cooling for 1 hour at which time an IR analysis shows the reaction to be complete.
